Involvement:General (knows how to use it) - Ownership:1 day to 1 week Pros:A good quality build, which is solidly constructed. There are LEDs to show power and when each relay is switch on. It has a nice 'click' when the relays toggle. It works out of the box with arduino nano and other devices I'm sure. You can connect to outputs Normally Open... Read more
Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week Pros:Economical price, small board size (72x49mm), 230VAC-capable relays with switchover contacts (so can do botu NO and NC). Tested with Raspberry Pi and its LVTTL (3.3V) output can drive the relay input high; in this state the board consumes 3.7mA of current from R... Read more

It activates the relays on "high trigger", which I find useful for my applications. Cons:This module has male headers. If you combine this module with an Arduino, female headers would've been more handy. OtherT... Read more
